Professor Tim Evans of Middlesex University discusses the report that higher-rate Scottish taxpayers have been heading south, explaining that it shows the truth of the Laffer Curve in action. He highlights the Basque Region's Mondragon Experiment which, in showing that there is a different way of running businesses, is effectively socialism without the state. Could it offer a future direction for the NHS? And he wonders how an increase in the UK's defence spending, announced by the Prime Minister, could work with so many other urgent calls on the public purse.
